functions

F(x) where x is the variable of one of the numbers within the domain. A domain is a number set. Domain is the input and range is the output (result) of the function.

For example you would have a function that goes like this.

f(x)=2x+20

your domain list would be (this would represent x)

X=1,3,5,7,9,11

Your range (the output) for this functions domain would be

f(1)=22
f(3)=26
f(5)=30
f(7)=34
f(9)=38
f(11)=42
